COURSE of the MONTH

Cisco Exchange 2010 and SendLabs

My ISP blocks port 25 so i am using a relay service to port 52525. It works when i implement a home router with no firewall perfectly but when i implement my Cisco router it doesnt go through even tho i created rules to allow it. i am confused. does cisco inspection look at the header and the way the packet is assembled and discard non port 25 packets because the signature isnt "correct"

also i am kind of hoping to NOT make my mail server an open relay! lol and only accept mail from the SendLabs servers. they have a list of IP's to allow but everything works on my send connector when it specifies allowed networks 0.0.0.0-255.255.255.255 but not when i delete that and add their IP range.

Who is Participating?

No, makes perfect sense. I have been installing WatchGuard products 10+ years and the install times are considerably less than any Cisco security product. I use Cisco for switching and routing and WatchGuard for all firewalling when able. Unfortunately some customers insist on Cisco, totally on name of course. They don't know any better. So yes, I would go with the X23. The new XTM devices are way more feature rich than their Edge series used to be as they run the same software as the bigger firewalls now.

yes it listening on 52525 and i can telnet to it inside. and like i said when i replace Cisco router with HOME unsecured router it works from external too. so it IS something to do with this cisco device...

I am about to try this and see what happens. would you say YES to Watchguard x23 OVER Sonicwall NSA 240? im torn between the two. As much as i like Cisco i find configs take longer than they should yet im CCNA certified. maybe im just stupid but id rather spend more time on other tasks then fighting with equipment. Iv heard EXCELLENT things about both Watchguard AND SonicWall. your thoughts?...
